| Abstract: | According to the characteristics and technical requirements of the blowout preventer shell, the casting technology was analyzed and the technology project of casting was developed. Based on the technology of numerical simulation to simulate numerically the hotspot position on valve-cover and feeding ability of the feeder. According to the simulation results,the origin of casting defects and hot spots was found,and the process could be optimized and improved by modifying the processing parameters. Finally,a ... |
